func (Grantee) MarshalXML added in v0.27.0 

func (x Grantee) MarshalXML(e *xml.Encoder, _ xml.StartElement) error

MarshalXML provides xml.Marshaler for Grantee.

XML scheme of Grantee is described in Amazon S3 docs https://docs.aws.amazon.com/AmazonS3/latest/userguide/acl-overview.html.

MarshalXML overrides default encoding of Grantee layout because currently xml.Marshal doesn't provide convenient approach to work with prefixes in XML namespaces. According to docs, Grantee.Type is an attribute from the namespace with 'xsi' prefix.

Here we use workaround proposed in corresponding Go issue https://github.com/golang/go/issues/9519#issuecomment-252196382.

func (*Grantee) UnmarshalXML added in v0.27.0
